STANOHION SUPPORT,

To all w/zom it may concern:

Be it known that I, Jo nn M. B. Lnwis, a citizen of the United States, residing at Lynchburg, in the county of Campbell and State of Virginia, have invented certain new and useful Improvements in Stanchion Supports, of which the following is a specification.

This invention relates to stanchion supports andinore particularly-to a support capable of adjustment transversely of the supporting rail and rotatable about its vertical axis, means being provided to normally maintain the stanchionin a position parallel with thestall curb.

An object of the present invention is the provision of adjustable"supporting means for stanchions which may be arranged to receive the heads of cows of different sizes.

A further object of the present invention is the provision of novel means for locking the adjustable supporting means in any desired position.

Other objects and advantages of the invention will be apparent during the course of the following description.

In the accompanying drawings, I have shown one embodiment of the invention. In this showing,

Figure 1 is a perspective View of the device secured to the horizontal stall rail.

Figure 2 is a transverse sectional view of the stall rail and the complementary menr bers secured thereto, showing the supporting bar in elevation.

Figure 8 is a vertical sectional view on the line 3-3 of Figure 2, and

Figure 4 is a detail view of the locking pin.

Referring to the drawings, the reference numeral 1 denotes a horizontal stall rail which is arranged at a suitable elevation above the stalls and in alinement with the stall curb. A pair of complementary members 2 and 3 is secured to the stall rail by suitable fastening means, such as bolts f and nuts 5. A portion 6 of each of these members is curved to conform to the shape of the stall rail. In the present instance, I have illustrated the stall rail constructed of a tube or pipe, but it is apparent that a member of any suitable shape may be employed for this purpose, and the complementary sections may be correspondingly altered to properly fit the stall rail. The complementary members are provided with extensions 7 and 8,

the said extensions being provided with transverse openings 9 and 10 adapted to be positioned in alinement with each other when the device isin position. .A supporting bar ll is arranged in these openings, the supporting bai beiiig provided with a projectioir or rib 12 on one face. As shown, the openings 9 and 10 are constructed to receive the ledge or rib on the supporting bar. Arranged at suitable intervals in the rib 12 is a plurality of'spaced grooves or recesses 1.3 adapted to receive thelocking pin to maintain the supporting bar in adjusted position. One of the complementary members isprovided with a secondopening 14 arranged above the opening 9, and a locking pin 15 is adapted to be positioned in this opening. As shown,'each end of the locking pin is arranged in a plane at substantially right angles to the body portiointhe two ends 16 and 17 being extended in different planes flo neach otlrer, A recess 18 is arranged in the complementary member 2 and when the locking pin is in position, thejend 16 is positioned in this recess and extends downwardly entering one of the grooves 13 in the supporting bar to prevent longitudinal movement of the supporting bar. The other end 17 of the locking pin is then in aborizontal plane and restsupon the top of the portion 7 of the complementary member 2.

The end of the supporting bar is provided with an opening for the reception of a sup porting member 19 which is held in said opening by means of a pin 20. The lower end of the member 19 is enlarged as at 21 and is provided with a cam face 22. A clevis 23 is arranged on the supporting member 19 and is provided with a corresponding cam face 24, the two cam faces being so constructed that the clevis will normally assume a position to bring the stanchion arms (not shown) in a plane parallel to the plane of the supporting rail and the stall curb. Each leg of the clevis is provided with openings 25 for the reception of a chain or other means for supporting the stanchion.

To adjust the supporting bar, the end 16 of a locking member must be removed from the groove 13 and this is accomplished by swinging the other end of the pin to a vertical position, the end 16 revolving in the re cess 18 and assuming the position shown in dotted lines in Figure 3 of the drawings.

When the arms of the stanchion are moved out of their normal vertical plane by an attendant in opening or closing the stanchion, they will immediately return to the proper position when released from the hands of the operator, due to the form of the cams 22 and 24.

It is to be understood that while I have described one embodiment of my invention, various changes in the shape, size, and arrangement of parts may be resorted to Without departing from the spirit of the invention or the scope of the subjoined claims.

Having thus described my invention, What I claim is: I

1. In a stanchionsupport, the combination with a horizontal stall rail, of complementary members adapted to be secured thereto and provided withregistering openings, a supporting bar arranged in said openings, a rib formed on one face of the supporting bar, said rib being provided with transverse grooves, a locking pin adapted to be received in one of said grooves and means for securing the stanchion to the supporting bar.

2. In a stanchion support, the combina: tion with a horizontal stall rail, of complementary members adapted to be secured thereto and provided with registering openings, a supporting bar arranged in said openings, a rib formed on one face of the supporting bar, said rib being provided with transverse grooves, one of said complementary members having an opening arranged above the rib or the supporting bar, and having a recess in one face communicating with said opening, a locking pin arranged in said opening, the end of the locking pin being disposed atan angle and adapted to be received in one of said transverse grooves, and means for securing the stanchion to the supporting bar.

3. In a stanchion support, the combina tion with a horizontal stall rail, of a supporting member adapted to be secured thereto and provided with an opening, said supporting member being further provided with a recess communicating with said opening, a supporting bar slidably mounted in said opening and provided with transverse grooves, a locking pin comprising a shank pivotally mounted in said supporting member, said pin having its ends disposed at right angles to said shank and to each other, one of said ends being disposed without the supporting member and the other of the ends disposed Within said recess and adapted to engage within one of the grooves of said supporting bar, and means for securing a stanchion to the supporting bar.

In testimony whereof I aflix my signature in presence of two witnesses.
